"random device not loaded; using insecure entropy" during boot

While booting -current I noticed a new warning introduced in r230230** 
<http://svnweb.freebsd.org/base?view=revision&revision=230230> (though 
it's not in 'dmesg' once booted):

FreeBSD/SMP: 1 package(s) x 2 core(s) x 2 SMT threads
  cpu0 (BSP): APIC ID:  0
  cpu1 (AP): APIC ID: 1
  cpu2 (AP): APIC ID: 4
  cpu3 (AP): APIC ID: 5
random device not loaded; using insecure entropy

I guess something's wanting random data before its been initialized?   
Once booted kern.random shows that it is loaded and working.
